The fact that you're still ignoring any of the substantive and responsive portions of my comments, bodes ill for this being a useful exchange.

It is quite possible I've misunderstood your queries and/or answered them inadequately. However, I'd like to think that the appropriate response in that case would be to clarify what you want, rather than simply taking it to mean no-one can give you what you want.

So the "human as controller" model doesn't simplify the problem, it just says "here, go solve the problem, somehow, and when you do, without the help of this model, you'll see that one of the six trillion neat things you can do is specify them in controls format".

I've mentioned a number of things that PCT does beyond that. For example, it shows that the first thing to look for in modeling are continuous analog variables integrated over a time period, with shorter time periods generally being represented lower in the control hierarchy than longer time periods. AFAICT, this is far from an obvious or trivial modeling distinction.

The fact that you chose not to comment on that, but instead dug in on justifying your initial position, suggests to me that you aren't actually interested in the merits (or lack thereof) of PCT as a modeling tool, so much as in defending your position.
